La présente invention concerne un procédé de télémétrie initiale (IN) pour un service de communication de machine à machine dans un système de communication mobile. La procédé de télémétrie initiale consiste à : reconnaître la présence d'un terminal entreprenant une télémétrie initiale ; déterminer si un service que le terminal souhaite recevoir est un service de communication mobile ou un service de communication de machine à machine ; et si le terminal veut recevoir le service de communication de machine à machine, définir pour le terminal un « indicateur indiquant d'utiliser des informations de partition de code de préambule de télémétrie (RP) pour une communication de machine à machine » ; et transmettre au terminal des « informations de commande relatives à la télémétrie initiale pour la communication mobile » comprenant l'indicateur. Les « informations de partition de code de RP pour une communication de machine à machine » représentent des informations sur des codes de RP disponibles dans le service de communication de machine à machine.
